} NOZZLE.

To all whom it Hwy concern Be it known that l[, MICHAEL JOSEPH GAL- VIN, of the town of North Bay, inthe district of Nipissing, in the Province of On tario, Canada,'have invented: certain new; and useful Improvements in Nozzles, olf

which the following is the specification,

My invention relates to improvements in nozzles and the object of invention is to devise means for automatically mixing -a stream of chemical solution with a stream 1 sists essentially of a main nozzle conical. in form, a water nozzle extending through the main nozzle, and discharging into the interior. of the'main nozzle in proximity of water passing under pressure from a hydrant through the nozzle and it conto the main nozzle outlet, a chemical solution supply nozzle also passing through the inain nozzle and discharging into the main nozzle in close proximity to the discharge outlet of the water supply nozzle and on that side of the discharge outlet of the water supply nozzle remote from the discharge outlet of the main nozzle as hereinafter more particularly explained by. the following specification.

Figure 1, is.a sectional perspective view of my device showing the water supply and chemital solution supply nozzles in full. Fig. 2, is a longitudinal section through my device. Fig. 3, is an enlargedcross section on line 00-54; Fig. 2.

In the drawings like characters ofreference indicate corresponding parts in each figure. 1 is the main nozzle comprising a hollow the apex of the cone. 3 is hose or other flexible .duct' connection leading to the hydrant or Water supply.

4 isa union connecting the hose 3 to the portion 5 of the main nozzle 1.

- 6 is a tapered nozzle fitting into a correspondingly tapered orifice 7, the discharge. outlet of the nozzle 6 being in' close proximity to the discharge outlet 2 of: the main nozzle. I 1 9 is a supplemental hose connection leadin to a suitable tank containing chemical so ution,the tank not being shown;

scribethe operation of the same. When the hose connections 3 and 9 have been connected to their respective sources of supply the Water fed by the hydrant is turned on and the water passesthrough the hose connection 3, through the nozzle 6 and through the outlet 2 of the main .nozzle 1.

The rush of water through the extreme point of the main nozzle creates a vacuum in the main nozzle *and in the chemical solution supply nozzle 11. This vacuum serves to draw the solution from the supply tank through the hose 9 and nozzle 11 so as to mix with the stream of water passing between the outlet of the nozzle 6 and the outlet of the nozzle 1.

It Willbe readily understood that such a device. will be found applicable to many purposes Where it is desired to mix a chemical solution with a stream of water under pressure such as in a hand fire extinguisher or in many forms of spray nozzles used for fumigating or treating of fruit trees and the like. conical body having a nozzle outlet 2 at Although, only one nozzle 11 has been shown through which the chemical solution is drawn it will, of course, be understood that a plurality of nozzles could be employed, each of such nozzles being connect-- ed to a separate receptacle, each receptacle containinga different solution. 'When these solutions are drawn through the chemical supply nozzles into the main nozzle they may combine and form agas which would add to the pressure of the stream through the main nozzle. This will be particularly valuable in cases where my device is employed as a fire extinguish er What I claim as my invention is.

A device of the class described c0mprising a primary nozzle, a secondary nozzle having a diagonally cutaway lower portion, said portion located adjacent the lower end of said primary nozzle, a casing for inclosing said nozzles comprising a' hollow conical body having an outlet opening at its apex, and closure means for the base of said conical body supporting said nozzles.
